It discusses old and new excavations and surveys as well. According to the importance of the material from these periods found at newly-excavated sites such as Kul Tepe Jolfa, Dava Goz Khoy, Lavin Tepe, and Qosha Tepe, we briefly describe the main stratigraphic and material data from these sites. Old and new datafrom excavations and surveys eventually lead us to a new chronological table for the 5th millennium BC in north/western (NW) Iran. The implications of the finds are discussed along with their limitations and future research directions.

KEY WORDS - Dalma; Pisdeli; 14C; updated Chalcolithic chronological table; NW Iran Introduction The period between the end of the Hajji Firuz and the beginning of the Kura-Araxes phenomena is one of the least known, yet most important eras in the ancient history and chronology of NW Iran. Previous studies demonstrated that the Chalcolithic is still among the least understood periods of prehistoric development in the region (Hamlin 1975; Dyson, Young 1960; Burney 1964; Pecorella, Salvini 1984; Voigt 1983). In the 5th and 4th millennium BC, complex societies developed in Eastern Anatolia, Northern (Upper) and Southern (Lower) Mesopotamia. This era, which is often referred to as the 'Post-Ubaid' period, was marked by major structural changes, such as the rise of social hierarchies, technological innovations and economic reorganisation, which eventually led to the emergence of proto-states and cities (Frangipane 2001; Marro 2012; Stien 2012). Some archaeological cultures and traditions that appeared during this period (5th millennium) have been brought to light in NW Iran. According to the latest data and material, it is impossible to draw a clear picture of the archaeology of the region during this period. Therefore, the real obstacle is the dramatic lack of absolute dating (with some exceptions), which makes it impossible to define the chronological extent of the Chalcolithic and construct a solid internal periodi-sation and properly articulated timeline for regional developments in this phase. DOI> 10.4312\dp.42.17 321 Akbar Abedi, Behrooz Omrani and Azam Karimifar Recent excavations outside Southern Mesopotamia provide a welcome opportunity to rethink the significance of the Post-Ubaid horizon from a different angle: several sites located in the Caucasus (Achun-dov 2007; 2011; Museyibli 2007; Lyonnet 2007b; Lyonnet et al. 2008; 2012; Marro 2010; 2012; Hel-wing 2012), central Anatolia or Cilicia (Caneva et al. 2012) have indeed yielded a number of features that are traditionally associated with the Post-Ubaid horizon: interestingly enough, however, these findings come from settlements whose cultural sequence seemingly developed from a totally different, that is non-Ubaid, background. Our discussion focuses mainly on two well-excavated sites: Kul Tepe Jolfa at the confluence of the Southern Caucasus, NW Iran and Eastern Anatolia, and Dava Goz Khoy, 5km north of the modern town of Dizaj Diz in the Khoy Plain in the Urmia Basin (Fig. 1). Together, these two sites span a chronological range encompassing the Dalma, Pisdeli (LC1 = Post-Ubaid), and LC2-3, roughly from 5000-3700 calBC. The two sites overlap in the LC1 and LC2 period (c. 4500-3750 calBC). The discussion also draws on data from key contemporaneous sites such as Tepe Lavin, Dagirmen Tepe Bostanabad, Qosha Tepe, Tepe Idir and Kohne Pasgah Tepesi to show the position of NW Iran during the 5th millennium BC on the basis of new discoveries. The paper also attempts to establish the settlement patterns and the dispersal of archaeological sites in NW Iran at Dalma, Pisdeli, and Chaff-Faced Ware/Chaff-Tempered Ware cultures, and highlights some of the fundamental changes that occurred in the structure of 5th millennium sites. The study reviews previous studies in Azerbaijan (NW) in the form of archaeological excavations, surveys and data recovered in the aftermath of Iran's Islamic Revolution. As such, new surveys at NW not only explain the causes of changes in socio-cultural patterns, but also clarify the undisclosed archaeological situation in eastern parts of Lake Urmia, and help to complete the Chalcolithic chronological table and the distribution map of the region during the periods mentioned. In our discussion, we prefer to use the important modified LC1-5 chronological terminology (Rothman 2001.5-9) as proposed by Gil Stein and Catherine Marro (Stein 2012; Marro 2012), and specific local sequences in order to avoid projecting a Southern Mesopotamian chronology and modes of organisation onto northern regions which developed social complexity through processes that were largely, if not completely, indigenous and different from those that characterised Southern Mesopotamia. A history of archaeological research in NW Iran The initial excavation in north-western Iran was made by Frank Earp, who opened four Bronze Age tombs in 1903 (Crawford 1975), and Theodore Burton Brown, who spent six weeks excavating eight separate trenches at Geoy Tepe in western Lake Urmia in 1948 (Burton-Brown 1951). Their work continued, with new methodologies, by Charles Burney, whose work focused on the very famous Yanik Tepe site. With his excavations at Yanik Tepe, Burney produced the first evidence for the appearance of the Kura-Ara-xes culture in north-western Iran (Burney 1961a; 1961b; 1962; 1964; see also Summers 2013a-b). Long-term archaeological investigations in north-western Iran continued at other sites, such as Hasanlu in the western Lake Urmia region, directed by Robert Dyson (Dyson 1965; 1968; 1972; Dyson, Muscarella Fig. 1. Map showing the locations of Kul Tepe Jolfa and Dava Goz Khoy in NW Iran. 322 Fifth and fourth millennium BC in north- -western Iran: Dalma and Pisdeli revisited 1989), Hajji Firuz (Voigt 1983), Dalma (Hamlin 1975) and Pisdeli (Dyson, Young 1960). Studies subsequent to these early excavations led to the identification of the Late Neolithic period in Hajji Firuz (6th millennium BC), previously regarded as belonging to the cultural horizon of Hasuan in Mesopotamia (Voigt 1983). Chalcolithic cultural material excavated at Dalma (5000-4500 calBC) was also comparable with that of the Halaf and Ubaid cultures in Southern Mesopotamia (Oates 1983). The Dalma period was followed by Pisdeli Culture (4500-3900/ 3800 calBC), which was contemporaneous with the Late-Ubaid/Post-Ubaid horizon. Geoy M/Gijlar C culture (4000-3500 calBC) is the final phase of the Chalcolithic period in north-western Iran, excavated and reported from Gijlar, Geoy M and Trench M at Yanik Tepe (Helwing 2004). The material culture of Yanik (Kura-Araxes), which takes its name from the Bronze Age Yanik Tepe site, belongs to the early Trans-Caucasian or Kura-Araxes culture (second half of the 4th to end of the 3th millennium BC), which spread through the Caucasus and the Urmia Basin. Its origin is unknown, but it has been observed in the valleys and foothills of three Caucasian republics (Azerbaijan, Armenia and Georgia), as well as north-western and western Iran, eastern Anatolia and the Levant (Sagona 1984; Kushnareva 1997; Rothman 2003; Batiuk 2005; Kohl 2007; Gopnik, Rothman 2011; Batiuk 2013; Abedi et al. 2014). During the final phase of prehistory in north-western Iran, the Middle and Late Bronze Age culture (2200/2000 to 1500 calBC) known as Urmia Ware, including painted monochrome and polychrome pottery, prevailed in this region. In the first half of the 2nd millennium BC, Urmia Ware extended over the Urmia basin and has been found in Haftavan VIB (Edwards 1981; 1983; 1986). Despite the general similarity between Urmia pottery, different regional names are used; for example, in eastern Georgia, pottery of this type is known as Trialeti-Vanadzor culture (Smith et al. 2009), in Azerbaijan as Uzarlik culture (Kushnareva, Lisitsyna 1986), and in Armenia as Karmirberd-Se-van culture (Abedi et al. 2009). In addition to the above-mentioned projects in northwestern Iran, other excavations and surveys carried out during recent decades in the Lake Urmia basin included Geoy Tepe (Burton-Brown 1951), Kordlar Tepe (Kromer, Lippert 1976; Lippert 1976), Tepe Dinkha (Dyson 1967a; Hamlin 1974), Haftavan Tepe (Burney 1970a; 1970b; 1972; 1973; 1974; 1975; 1976a; 1976b; 1979a; Edwards 1981; 1983; 1986), Tepe Ahranjan (Tala'i 1983), Tepe Gijlar (Pe-corella, Salvini 1984; Belgiorno et al. 1984), Kul Tepe of Marand (Kroll 1990), and Gol Tepe (Tala'i 1984). In addition, surveys were undertaken in northwestern Iran (Kambakhsh Fard 1967; Soleki 1969; Soleki, Soleki 1973; Swiny 1975; Pecorella, Salvini 1984), the Salmas valley (Kearton 1969; 1970) and the Solduz plain (Dyson 1967b), around Lake Urmia (by a German team) (Kleiss, Kroll 1979; 1992; Kroll 1984; 2005) and in the Meshkin Shahr area (Burney 1979b; Ingraham, Summers 1979). Since the 1979 Revolution in Iran, archaeological research has included Early Bronze Age settlement patterns and site distribution in north-western Iran (Omrani 2006; Omrani et al. 2012; Summers 2013a), a survey in Eastern Azerbaijan province (Khatib Shahidi, Biscio-ne 2007; Biscione, Khatib Shahidi 2006), a systematic survey at Tepe Baruj (Alizadeh, Azarnoush 2003a; 2003b) and the Mughan plain (Alizadeh, Ur 2007), and excavations at Lavin Tepe (Nobari et al. 2012), Nader Tepesi (Alizadeh 2007), Qosha Tepe in the Meshkin Shahr area (Nobari, Purfaraj 2005), Kohne Pasghah Tepesi (Maziar 2010), the Iron Age cemetery of Masjed Kabood in Tabriz (Nobari 2000 [1379]; 2004 [1383]), the Qale Khosrow and Ardebil Survey (Azarnoush et al. 2006), Qalaychi and Tepe Rabat (Kargar 2005; Kargar, Binandeh 2009), Zard-khaneh of Ahar (Niknami 2011), and Kohne Shahar (Ravaz) (Alizadeh et al. 2015). Apart from these excavations and surveys, many others have yet to be published. The main problems for archaeology in north-western Iran are the lack of systematic and intensive long-term excavations and surveys and a shortage of reliable publications, as well as inaccurate and uncali-brated dating of old excavations and a shortage of multidisciplinary works. In recent years, most excavations in north-western Iran have taken place in the course of salvage and dam construction projects. Kul Tepe Jolfa and Dava Goz Khoy in NW Iran Kul Tepe Jolfa The Kul Tepe site (E 45° 39' 43"- N 38° 50' 19", 967m a.s.l.; Figs. 1-2) is located near the city of Ha-dishahr, 10km further to the south of the Araxes River. Kul Tepe is a multi-period tell, about 6ha in extent and rising 19m above the surrounding land. The site was originally discovered by an expedition in the province of East Azerbaijan in 1968 under the supervision of Sayf Kambakhsh Fard (Kambakh Fard 1968), and was later reported by other authors as well (Kliess, Kroll 1992; Kroll 1884; Edwards 1986; Omrani 1994). Kul Tepe is located precisely in the north-western corner of Iran, which is the 323 Akbar Abedi, Behrooz Omrani and Azam Karimifar gateway between the Southern Caucasus and northwestern Iran, about 50km from the famous Kultepe site at Nakhichevan. Kul Tepe is located next to a broad valley, at the centre of the highlands and at the crossroads of major routes linking the Iranian plateau to Anatolia and the Caucasus to Northern Mesopotamia (Fig. 1). This strategic location is further enhanced by the region's wealth in natural resources, which include rich copper and salt deposits. The first season of excavation at Kul Tepe were carried out from June to August in 2010 (Abedi et al. 2014). Because of the huge quantity of material and deposits at Kul Tepe, the site needs more research and excavation to better understand the cultural situation in the region. The second season of excavation was from August to October 2013 in order to answer certain questions about the region and extend the studied areas. The first and second seasons of excavation were primarily aimed at clarifying the chronology and settlement organisation, and answering some fundamental questions (such as the transition process from the Late Chalcolithic to the Early Bronze Age), identifying different cultural horizons, including the Proto-Kura-Araxes and Kura-Araxes I periods, and also outlining the cultural situation in the region during prehistoric and historical periods. The initial aims were to establish periods of occupation and to obtain a stratigraphically controlled ceramic sequence for the Jolfa region and the northern part of north-western Iran. More specifically, Kul Tepe, was excavated for two main reasons: Kul Tepe periods Cultural phases Range (calBC) VIII Early Chalcolithic (Dalma) 3m deposit 5000-4500 VII LCi: Pisdeli/Hasanlu VIII 1.5m deposit 4500-4200 VIB LC2: Chaff-Faced 3m deposit 4200-3900 VIA LC3: Chaff-Faced 3m deposit 4000/3900-3750 V Kura-Araxes I 3.5-41TI deposit 3400/3350-3100/3000 IV Kura-Araxes II, III 7.5-8m deposit 3000/2900-2500 III Middle Bronze Age (Urmia Ware) 1m deposit 1st half of 2nd millennium II Iron Age III, Urartian 50cm deposit 8th-6th century I Achaemenid 1m deposit 6th-4th century © to determine the presence of Late Chalcolithic followed by Early Bronze Age occupation levels; © more importantly, to test for the presence of a probable 'transition' period between the Late Chal-colithic and Early Bronze Ages and the existence of Proto-Kura-Araxes and Kura-Araxes I periods. Based on the results of the first and second seasons of excavation, eight main periods were identified, which provide evidence of a continuous sequence (except in the Iron Age I and II periods) and significant material was found from the Dalma (Period VIII), Pisdeli (= LC1: Period VII), Chaff-Faced Ware horizons (LC2-3: Period VIB and VIA), Kura-Araxes I (Period V), Kura-Araxes II (Period: IV), Middle Bronze/ Late Bronze Age (Urmia Ware, Period: III), Iron III (Period II), and Urartian/Achaemenid (Period I) periods. As a result of the excavation of 24m deposits it was established that it consists of 3m deposit of Dalma, 1.5m of Pisdeli, 6m of CFW horizon (Kul Tepe VIB and VIA), 3.5-4m of Kura-Araxes I, 7.5-8m of Kura-Araxes II, 1m of Middle and Late Bronze Age with typical Urmia Ware and finally 1.5m of Iron III with Urartian and Achaemenid materials (Abedi, Omrani 2013; Abedi et al. 2014) (Figs. 3-4, Tab. 1). Interestingly, Mary Voigt and Robert Dyson, based on Pisdeli Tepe materials and site sequence, suggested a transition between the Dalma and Pisdeli periods, with no gap between them. They proposed that Pisdeli culture developed locally (Voigt, Dyson 1992. 174). The Kul Tepe excavation supports this notion. Late Chalcolithic layers were discovered in the deep sounding, in Trench III, with no break after the Dalma (Fig. 5) materials. Based on pottery type, form, design and surface treatment and the sequence in which they occur, and on other Late Chalcolithic materials at Kul Tepe, three sub-phases were identified: Kul Tepe VII = Pisdeli (LC1 = Post-Ubaid), Kul Tepe VIB = LC2 (Chaff-faced/ Chaff-tempered), and Kul Tepe VIA = LC3 (Chaff-tempered) cultures. Tab. 1. Sequence at Kul Tepe based on excavations in 2010 and 2013. The lowest Late Chalcolithic layers (LC1, Post-Ubaid: 4500-4200 calBC) include black-on-buff, so-called Pisdeli-type painted pottery. This pottery repertoire is almost entirely limited to geometric or non-representational designs; emphasis is on horizontal banding made with straight lines, which may border some design elements. All 324 Fifth and fourth millennium BC in north- -western Iran: Dalma and Pisdeli revisited Fig. 2. General view of Kul Tepe, view from the north. calBC), termed Kul Tepe VIB, and LC3 = Chaff-faced Ware (3900-3700 calBC), termed Kul Tepe VIA. According to the stra-tigraphic section in the upper part of Trench III and the lower part of Trench II, 6 m of deposits relate to Kul Tepe periods VIB (LC2) and VIA (LC3) (Fig. 7). The chronological framework presented here is based on three lines of evidence: (1) rim and decoration typology (embedded within the stratigraphic sequence), (2) pottery technology, (3) radiocarbon dates. the painted pottery of this period bears monochrome and matte paint, with colours ranging from brown to black. Generally, painting is limited to bowls and small pots. Most of the pottery of the Late Chalcoli-thic consists of buff to reddish chaff-tempered fabric. All of the painted sherds are painted black and brown on buff or brown and red (reddish-brown), and include geometric designs such as oblique and diagonal lines beneath the rim. Another diagnostic design is hatched and plaid on jars and bowls (Fig. 6). Late 5th millennium Chaff-Faced Ware appears alongside Ubaid-related (Pisdeli) black on buff during LC 2-3. Two main periods can be distinguished, mainly based on ceramic evidence, but supported by additional information from other kinds of artefact. These periods are LC2=Chaff-faced Ware (4200-3900 Fig. 3. Kul Tepe. Stratigraphic sections of trench I and IV small-scale excavations. Late 5th millennium Chaff-faced or Chaff-tempered ware appears alongside Ubaid-related black on buff during LC 2-3 (Helwing 2012). In the later phase of the Chalcolithic, most of the pottery production is buff, chaff-tempered and chaff-faced. The repertoire of shapes consists mainly of simple everted bowls, pots and jars, sometimes decorated with a row of bosses below the rim or an annular coil around the shoulder. Rims decorated with incisions or impressions are common to most pottery of this LC2 and 3 type at this site. Chaff-faced and chaff-tempered pottery with combed surfaces is typical of the Late Chalcolithic of Southern Azerbaijan in general and the Nakhichevan region and north-western Iran in particular, where it has been termed 'Kultepe culture'. Similar pottery was found at Kultepe I, Khalaj, Erebyengicesi, Sederek (Bakh-shaliyev et al. 2009; Marro et al. 2011), Kul Tepe of Marand (Kroll 1990), Tepe Baruj (Ali-zadeh, Azarnoush 2003b) and Tepe Dava Goz Khoy (Abedi, Omrani 2013). But close comparisons may also be made over a much wider area, which includes Eastern Anatolia, the Urmia basin and Northern Mesopotamia, where similar traits are designated as part of the 'Marand culture' in Iran (Kroll 1994), or 'Chaff-faced ware culture', also called 'Amuq (E)-F', in Turkey and Northern Syria (Braidwood, Braidwood 1960). 325 Akbar Abedi, Behrooz Omrani and Azam Karimifar Fig. 4. Kul Tepe. Step trench II and deep trench II; stratigraphic section of trench II and III soundings. 326 Fifth and fourth millennium BC in north- -western Iran: Dalma and Pisdeli revisited However, if we focus on the main features of the pottery assemblage from Kul Tepe, it is clear that this repertoire shares close similarities with sites located in the northern parts of the Araxes River, especially sites like Ovgular Tepesi, Kultepe, Alikomek Tepesi, Mentesh Tepe and Leila Tepe in Azerbaijan, Sioni and most related sites in Georgia, Aratashen in Armenia, and some sites in eastern Turkey and northern Mesopotamia. Dava Goz The settlement of Dava Goz is situated about 10km south-west of Khoy and 5km north of Dizaj Diz town. Dava Goz is a small site, measuring about 100x100m (approx. 1ha). The site has been completely destroyed by modern agricultural activities, which prevents mapping of the whole topography (Fig. 8). The stratigraphy of the settlement is now well understood, and covers the Late Neolithic/Transitional Chalcoli-thic (Hajji Firuz/Dava Goz I = Period I) and Chalco-lithic (Pisdeli = LC1 = Period II and CFW horizon = LC2 = Period III) phases of the regional culture north of the Lake Urmia basin (Fig. 9-10). The first season of excavation at Dava Goz lasted from June to August 2012. Dava Goz is a horizontal site that relates to the Hajji Firuz, Dava Goz (Transitional Chalcolithic), Pis-deli and CFW cultures. Hajji Firuz materials are mainly located at the centre of the site. It seems clear that during Hajji Firuz Period this was seasonal camp site, because the layers are no more than 0.5m thick. However, the Pisdeli materials were mainly in the western part of the site, with a cultural layer of 2.5-3m. Actually, Dava Goz is one of the few well-excavated settlements to yield new information on developments in the Lake Urmia basin communities between the 6th to 4th millennium BC, and on their relationships with contemporary Caucasian cultures, as well as with those located further west and south in Eastern Anatolia and in the Syro-Mesopotamian region. Dava Goz overlaps in the LC1 and 2 periods with Kul Tepe VII and VIB (c. 4500-3900 calBC). Like Kul Tepe, the Dava Goz pottery repertoire is divided into two, painted and unpainted, through LC 1 and 2. The pottery assemblage is the same as at Kul Tepe and encompasses cultural layer at the site (Fig. 10). 5th millennium BC and the problem of chronology in NW Iran Obviously, the (absolute and relative) chronology and internal periodisation of the Chalcolithic period have been, and still are, the subject of much research and debate. It would appear that the difficulties encountered in establishing the chronological time limits of this cultural phenomenon, which still continue to fluctuate, are mainly due to the dearth of absolute dating in the Southern Caucasus (with only a few exceptions), while over the course of time there seems to have been a general tendency, supported by new dating, to shift the time limits of (or at least the starting time) higher up the time scale. After three decades of stagnation in archaeological activities in NW Iran, valuable work has been done in recent years. Almost all the excavated sites in this region are situated around the Lake Urmia, while information about other parts of the region is lacking, and different parts of the region and its prehistory have received unequal attention. While a considerable area of the western and southern parts of the Lake Urmia basin has been explored relatively comprehensively, eastern and northern parts remain largely archaeological terra incognita. Previous studies put the Dalma period in the second half of 5th millennium BC (Hamlin 1975; Hole 1987), although only one date was available from this period (Hole 1987). The rare scientific excavations carried out concerning the Dalma period in its homeland (NW Iran) with only one 14C date has limited our ability to establish a solid chronological table for the whole of the Dalma period. The same limitation has also risen for the Pisdeli period, for which only rare radiocarbon dates are available, and with an imprecise and faulty time span (late 5th to early 4th millennium BC). Prior to the Kul Tepe Jolfa and Dava Goz Khoy excavations, it was not possible to establish appropriate and precise periodisation and chronology between Hasanlu VIII and VII in the chronological sequence of NW Iran (Tab. 2). The 5th millennium is considered as the largest lacuna in our understanding of the developmental sequence in NW Iran, although new excavations with absolute radiocarbon dates have shed some new light on the Chalcolithic period in the region. Dalma period in NW Iran (5000-4500 BC) In the first half of the 5th millennium BC (Early Chal-colithic), the remarkably homogeneous Dalma ceramic assemblage spread throughout much of northwest and western Iran. Dalma is an unusual ceramic phenomenon for this time range: a widespread, but technically and stylistically homogeneous material cultural tradition, at home in a topographically severe highland region. The Dalma period is particu- 327 Akbar Abedi, Behrooz Omrani and Azam Karimifar Fig. 5. Kul Tepe VIII (Dalma) pottery, Tr. III and IV. larly interesting because of the extremely large geographic spread of its ceramics, ranging from the 'widely separated mountain plains such as the Urmia basin and the Mahidasht and the Kangavar regions' to the Hamrin region of eastern Iraq, where it occurs in combination with typical Halaf and Ubaid pottery. Similar ceramic types have also been found in the Caucasus Mountains. The first evidence of Dalma culture was found at the south-west end of Lake Urmia, at Tepe Dalma and Hasanlu in 1958. Dalma materials have also been reported from Hajji Firuz, Pisdeli and Tepe Seavan. Apart from the mentioned excavations, various surveys have been carried out by different expeditions (Dyson 1962; Hamlin 1975; Henrickson, Vitali 1987; Hole 1987; Levine, Young 1987; Solecki, Solecki 1973; Vandiver 1985; Voigt, Dyson 1992; Young, Levine 1974; Pecorella, Salvini 1984; Kroll 1984; 1994; Tonoike 2009; Vitali, Henrickson 1987; Hamlin 1975; Hole 1987b; Oates 1983.261; Voigt, Dyson 1992). 328 Fifth and fourth millennium BC in north- -western Iran: Dalma and Pisdeli revisited Fig. 6. Kul Tepe VII (LC1) Pisdeli type pottery. The series of radiocarbon dates now available from Kul Tepe Jolfa, Tepe Dava Goz and one calibrated date from Tepe Dalma, make it clear that the frequently mentioned date of 4215 ± 84 calBC from Tepe Dalma (second half of 5th millennium), and suggested dates of 4100-3700 calBC for Dalma culture said to date the Middle Chalcolithic, are much too recent in NW Iran and should now be revised (Hamlin 1975; Voigt, Dyson 1992; Henrickson 1985.70). New radiocarbon dates from Kul Tepe Jolfa and Dava Goz suggest the first half of the 5th millennium calBC for the Dalma period in NW Iran (5000-4500 calBC) (Abedi et al. 2014; Abedi, Omrani 2013). The available dates argue that the Dalma tradition flourished during first half of the 5th millennium calBC in NW Iran, spreading south to the Central Zagros in the second half of 5th millennium. Valuable work has been done on prehistoric archaeology in Iranian Azerbaijan in the form of archaeological excavations, surveys and data recovered in the aftermath of Iran's Islamic Revolution. Recent excavations at Kul Tepe Jolfa (Abedi et al. 2014; 2009), Tepe Ahranjan (Talai 1983; Kargar 1994), Tepe Lavin (Nobari et al. 2012), Qosha Tepe (Nobari, Pur-faraj 2005), Tepe Idir (Hesari, Akbari 2007), and Tepe Baruj (Alizadeh 2001; Alizadeh 2003a; 2003b) have yielded fascinating new information about Dal-ma culture. Apart from these excavated sites, more than 100 Dalma and Dalma-related sites have been brought to light by old and recent surveys in NW Iran. Recently, scholars have suggested a combination of factors, such as trade and exchange, the movement of material goods and information, migration, diffusion, and local emulations of foreign styles to explain Dalma cultural phenomena (Voigt 1983; To-noike 2009). The settlement pattern and distribution of Dalma sites in NW Iran suggests it can be divided into two types: (1) permanent settlements in fertile inter-mountain valleys, and (2) temporary seasonal camp sites in the highlands of Zagros, the Caucasus and other highlands of north-west Iran. Yukiko Tonoike (2009) concluded that a village-based form of seasonal migration (transhumant pastoralism) was the most likely scenario, whereby small groups of nomads moved between villages with which they maintained relationships, possibly through kinship. Transhumance is a specialised form of pastoralism that is still based on permanent settlements, but involves the seasonal movement of the herd between pastures (Abdi 2003). What is important in this respect is the chronological differences between north-western Iran and the Central Zagros regions, where the Dalma period ranges from 4100 to 3700 calBC, whereas this time coincides with the LC 2 and 3 (Chaff-Faced Ware Cultures) periods in north-western Iran. Pisdeli (Hasanlu VIII/LC1 Post-Ubaid) period (4500-4300/4200 BC) During the mid-5th millennium or slightly later (LC1, Post-Ubaid: 4500-4200 calBC) black-on-buff, so-called Pisdeli culture was gradually replaced throughout the southern, western and northern regions of the Lake Urmia basin. Pisdeli, also known as Hasan- 329 Akbar Abedi, Behrooz Omrani and Azam Karimifar lu VIII or middle Chalcolithic, and was first defined at Pisdeli (Dyson, Young 1960) and reported from Hajji Firuz (Voigt 1983) and Hasanlu (Dyson 1958). Interestingly, based on Pisdeli Tepe materials and its sequence, Mary M. Voigt and Robert Dyson (1992. 174) suggested a transition between Dalma and Pis-deli with no gap between these two periods, and proposed that Pisdeli culture developed locally. Most studies of the Pisdeli period relate to the few famous typical sites, including Pisdeli (Dyson, Young 1960), Geoy Tepe (Burton-Brown 1951), Yanik Tepe (Burney 1961a; 1961b; 1962; 1964), and Tepe Gijlar (Bel-giorno et al. 1984). Apart from these excavations, various surveys have been brought to light prominent data concerning this period (Belgiorno et al. 1984; Kroll 1984; 1990; 2005). Recent discoveries in NW Iran have yielded fascinating new information about Pisdeli culture. Excavations at new, well-stratified sites at Kul Tepe Jolfa (Abedi et al. 2014) and Tepe Dava Goz Khoy (Abedi, Omrani 2013) provided new information about the Pisdeli period with new radiocarbon dates. At Kul Tepe Jolfa 3m deposits of Pisadeli period were unearthed. Kul Tepe VII relates to this phase with both painted and unpainted pottery. New radiocarbon dates from Kul Tepe VII give dates around 45004300/4200 calBC for the Pisdeli period. The excavation at Dava Goz Khoy has also yielded very strong materials related to this period, with complete typi- cal Pisdeli ware. 14C absolute dating from Dava Goz II suggests the same date for this time span. In the course of recent work, Tepe Ahranjan (Kargar 1994) and Tepe Lavin (Nobari et al. 2012) have provided new information about this period. Apart from the recent excavations mentioned, new surveys have produced new insights and perspectives on the chronological enigma of NW Iran during the Pisdeli period. Barbara Helwing (2004) suggests a threefold chronological break-down for the Late Chalcolithic in NW Iran and places Pisdeli Tepe in the LCH1 period as the oldest assemblage (= Hasanlu VIII) preceding both Yanik Tepe M, and Geoy Tepe phases N and M and even Gijlar C. She also proposes that the Grey Burnished Ware of Geoy Tepe N is an early stage of LCH2 and eventually Chaff-faced/Chaff-tempered ware for the developed stage of LCH2. This division was later approved by Michael Danti et al. (2004). Excavations at Kul Tepe Jolfa and Dava Goz Khoy shed some new light on Pisdeli dates in NW Iran. These dates, accompanied by new recalibrated old samples from the Hasanlu project (Danti et al. 2004), lead us to a comprehensive chronology for the Pis-deli period. New radiocarbon calibrated dates from all Pisdeli-related sites suggested a date of 45004300/4200 calBC for the Hasanlu VIII (LC1, Pisdeli, Kul Tepe VII, Dava Goz II) period. Fig. 7. Kul Tepe VIA (LC3) Chaff-faced pottery. 330 Fifth and fourth millennium BC in north- -western Iran: Dalma and Pisdeli revisited LC2; Chaff-faced/Chaff-tempered ware; Kul Tepe VIA/Dava Goz III (4300-3800/3700 calBC) At present, the Chaff-faced Ware (CFW) or LC2 period is the largest lacuna in our understanding of the developmental chronological sequence in NW Iran. Excavations and published material on CFW or after Pisdeli material in NW Iran are rather scant, and raise many questions. Recently, new data from Kul Tepe Jolfa (Abedi et al. 2014), Dava Goz Khoy (Abedi 2013), Kohne Pasgah Tepesi (Maziar 2010), Dagimentepe Bostanabad (Chaichi, Omrani 2010) have shed some new light on LC2-3 CFW period in NW Iran. Apart from excavations, old and new surveys have provided results regarding the distribution and expansion of CFW phenomena in NW Iran. More than 100 sites were brought to light from all surveys in Iranian Azerbaijan from different districts, such as: Jolfa, Marand, Khoy, Shabestar, Salmas, Urmia, Ushnaviyeh, Naqadeh, Piranshahr, Mahabad, Bukan, Shahin Dezh, Tekab, Malekan, Bonab, Marag-heh, Ajabshir, Azarshar, Tabriz, Ahar, Heris, Bostanabad, Hashtrood, and Sarab. Prior to the Kul Tepe Jolfa and Dava Goz Khoy excavations, only scant materials related to this period had been reported and published (Burton-Brown 1951; Burney 1964; Kroll 1990; 2005; Helwing 2005; Maziar 2010). Recent 14C radiocarbon dates from Kul Tepe Jolfa VIB and VIA and Dava Goz Khoy III suggest a date of c. 4200-3700 BC for the LC2-3 CFW tradition in NW Iran. Recently, fresh dates from adjacent regions - the Southern Caucasus and Northern Mesopotamia - have confirmed this date for CFW (Marro 2010; 2012; Stien 2012; Helwing 2012). Fig. 8. General view of Dava Goz, View from north-east. The stratigraphic section at Kul Tepe revealed that 2-5m of strata belong to LC1 and LC2-3, respectively. Kul Tepe VII revealed both black-on-buff painted and unpainted assemblages. Painted samples comprised a small percentage of the pottery repertoire; the situation was the same at Dava Goz, where unpainted ware accounted for the majority of the assemblage. Discussion The Chalcolithic is one of the most important, but also a very ambiguous period in NW Iran. Only sparse and scant studies have been done around the Lake Urmia basin at Geoy Tepe (Burton Brown 1951), Pisdeli Tepe (Dyson, Young 1960), Yanik Tepe (Burney 1961a; 1961b; 1962; 1964) and Tepe Dalma (Hamlin 1975), and some other sites are known from surveys (Pecorella, Salvini 1984; Kroll 1984; 1990) but information is limited to surface collection. The most significant obscurity is due to the lack of accurate 14C dating in chronology of NW Iran. Only scant 14C uncalibrated dates were available from Pisdeli and Tepe Dalma during the 1960s and 1970s and with one or two samples it is impossible to construct a chronology of the region. So the real obstacle is the dramatic lack of absolute dates (with some exception) which makes it impossible to define the chronological extension of the Chalcoli-thic and build up a solid internal periodisation and properly articulated timeline for regional developments in this phase. After three decades of stagnation in archaeological activities in NW Iran, valuable work has been done on the prehistoric archaeology of the region in recent years. Almost all excavated sites in the region are around Lake Urmia, while information about the other parts of the region is lacking, and different parts of the region and its prehistory have received unequal attention. While a considerable area of the western and southern parts of the Lake Urmia basin has been explored relatively comprehensively, the eastern and northern parts remain largely archaeological terra incognita. However, the advance of research at well-stratified sites at Kul Tepe Jolfa, 331 Akbar Abedi, Behrooz Omrani and Azam Karimifar Dava Goz Khoy with 14C radiocarbon dates has shed some new light on this hitherto poorly understood chronology. The Dalma culture is one of the most intriguing phenomena of NW and Western Iran. The broad outlines of Dalma material culture are well known by now, and it is renowned for its elaborately decorated pottery. Other aspects of Dalma society, however, are still poorly understood. The chronology and the origin of Dalma society is a matter of much debate, and likewise our insights into Dalma economic or social organisation are generally based on mere speculation. In the light of the available data, especially the pottery repertoire and recent radiocarbon dates, it demonstrates that the Dalma phenomena or tradition emerged after the Hajji Firuz period (c. 6000-5400 calBC) with a short gap in NW Iran. From this point on, two scenarios are possible for the spread of Dal-ma in NW Iran; first, we can surmise it as a foreign (alien) imported tradition from outside the NW region (western or southern region), or it can be seen as a local derivative of a previous culture (Hajji Firuz). In this respect, it is felt that Dalma in the Urmia Basin of NW Iran was the ultimate result of a long and locally founded sequence of late Neolithic (Hajji Firuz) development. As mentioned above, with new radiocarbon dates for the Dalma tradition (c. 5000-4500 calBC) it seems likely that some sites can fill this 400-year gap between the two periods, which we regard as a transitional period. A similar conclusion can be drawn from the survey results in the region. Provenance analysis has also shown that all Dalma ceramics were produced locally (Vitali, Henrickson 1987; Tonoike 2009). It seems clear that only pottery production changed during the Dalma period compared with the preceding Hajji Firuz, but not all Dalma sites clearly suggest any marked discontinuity in other aspects of the material culture. Obsidian analysis in NW Iran (Khademi Nadooshan et al. 2013) indicates that during the Chalcolithic period an extensive and local obsidian trade was practiced by some transhumant or pastoral groups between the Lake Urmai basin and the highlands of the Caucasus. Local regional and inter-regional trade played an important role in the distribution of Dal-ma culture to adjacent regions. In addition to trade, easy access to main routes, the exploitation of various resources, interaction between lowland settlements and highland pastoral sites by some transhumant or pastoral groups can be considered key factors in the distribution of Dalma culture. Excavations at Kul Tepe Jolfa and Dava Goz Khoy unravelled the problem of the Chalcolithic of NW Iran after the Dalma period and divided it into two main periods: Pisdeli (LC1 = Kul Tepe VII; Dava Goz II) (4500-4200 calBC) with typical painted pottery (black-on- buff); and the Chaff-Tempered/Chaff-Faced Ware tradition (LC2 and 3 = Kul Tepe VIB and VIA; Dava Goz III) (4200-3700 calBC). Recent discoveries in NW Iran make it possible to draw precise conclusions about the final phases of the Late Chalcolithic. The new excavations in the last decade concerning the Chalcolithic in the Southern Caucasus (Ovcular Tepesi, Leyla Tepe) (Achundov 2007; 2011; Museyi-bli 2007; Lyonnet 2007b; Lyonnet et al. 2008; 2012; Marro 2010; 2012; Helwing 2012), Eastern Anatolia (Frangipane 2012) and Northern Mesopotamia (Sti-ent 2012) enable scholars to define the chronological range of the Chalcolithic and build up a solid internal periodisation and properly articulated timeline for regional developments in this phase (Marro 2012). Recent excavations in NW Iran substantiate that post-Ubaid finds come from settlements whose cultural sequence seemingly develops from a very different, that is, non-Ubaid background. In her most recent publication, Marro (2012) used the term 'post-Ubaid' Hasnlu sequence NW chronology Kul Tepe sequence Dava Goz sequence Date Hasanlu VII Kura Araxes II Kul Tepe IV - 3000-2500 calBC - Proto-Kura Araxes/Kura-Araxes I Kul Tepe V - 3400/3500-3000 calBC - LC 3, CFW Kul Tepe VIA - 3900-3700 calBC - LC 2, CFW Horizon Kul Tepe VIB Dava Goz III 4200-3900cal calBC Hasanlu VIII (Pisdeli) LC 1, Black-on-Buff Kul Tepe VII Dava Goz II 4500-4200 BC Hasanlu IX (Dalma) Dalma Kul Tepe VIII - 5000-4500 calBC Hasanlu X (Hajji Firuz) Late Neolithic/ Transitional Chalcolithic Kul Tepe IX Dava Goz I 5400-5000 calBC Tab. 2. Chronological table for NW Iran with new chronology from Kul Tepe and Dava Goz. 332 Fifth and fourth millennium BC in north- -western Iran: Dalma and Pisdeli revisited for the period from 4500 to 3800 calBC. She divided this phenomenon into 'Ubaid' and 'non-Ubaid' land. She focused on interactions between the lowlands and the highlands, with a reassessment of the available data from a non-Me-sopotamian perspective. She used different terms for this spreading phenomena - 'Chaff-Faced Ware oikoumene' (Marro 2010), 'Standardized ware oikoumene' (Marro 2012) - for a period after Ubaid as a result of both interruptions and continuity. She suggests that this widespread expansion of CFW may have been the result of, or is related to the economic and productive sphere (Marro 2012). According to the available data, post-Ubaid CFW culture in the Southern Caucasus and NW Iran is indeed related to Mesopotamia, but it is not a Mesopotamian culture per se. Rather, the centre of gravity of this culture probably lies between the Upper Euphrates, the Kura Rivers and the Lake Urmia basin. The CFW cultural horizon encompasses the highlands and Upper Mesopotamia, which are thus part of the same oikoumene. However, it should be stressed that the CFW sites attested over this vast territory probably had different functions and were constituents of a complex economic system (Marro 2010). For the post-Ubaid horizon, six major 'ceramic provinces' or 'cultural provinces' were grouped by Marro (2012): (1) Southern Caucasus; (2) Upper Euphrates province; (3) western Euphrates province; (4) Kha-bur cultural province; (5) the Balikh region; and (6) the Cilician province. With new excavations in NW Iran (at Kul Tepe Jolfa, Tepe Dava Goz Khoy and Kohne Pasgah Tepesi), a seventh group can be suggested, with typical Pisdeli (LC1 = Kul Tepe Jolfa VII and Dava Goz II) and CFW (LC2 and 3 = Kul Tepe Jol-fa VIB and VIA and Dava Goz III) materials. We think this group is similar to the Southern Caucasus group and is homogeneous in many aspects, but it seems that this was the case only during the LC2 and LC3 periods, while LC1 is absent in most parts of the Southern Caucasus. During LC1, a close relationship can be clearly seen with the Upper Euphrates (sites Norsun Tepe, Korucu Tepe and Tulin Tepe), Khabur Fig. 9. Typical Late Neolithic/ Transitional Chalcolithicpottery from Dava Goz. (Gawra XII) and Balikh regions (sites Tell Zeidan LC1 and LC2, and Hammam et-Turkman IVD and VA). Throughout LC2, contacts increased with sites in the Southern Caucasus (Ovcular Tepesi, Leyla Tepe, Men-tesh Tepe etc.), Upper Euphrates (Norsun Tepe IIA), Khabur (Gawra XI-IX) and Balikh regions (Tell Zei-dan LC2 and Hammam et-Turkman). Recent excavations show that the development from Pisdeli (LC1 = Kul Tepe Jolfa VII and Dava Goz II) to CFW (LC2 and 3 = Kul Tepe Jolfa VIB and VIA and Dava Goz III) took place without interruption in NW Iran, which is the case in Balikh and Khabur 'cultural province'. After the LC 3 period onwards, the CFW tradition was superseded in NW Iran by a widespread expansion of famous Kura-Araxes phenomena, which flourished from the highlands of Transcaucasia and NW Iran. Settlement stratigraphy accomplished with new radiocarbon dates from Kul Tepe Jolfa show that period V (Proto-Kura-Araxes-Kura-Araxes I) with 3400 calBC launch into this period without any interruption. According to the pottery and other materials, 333 Akbar Abedi, Behrooz Omrani and Azam Karimifar it seems probable that a transition occurred between the end of the Chalcolithic and beginning of Kura-Araxes culture (Marro 2009). We think this is what occurred in most parts of NW Iran. Only some parts of the southern end of Lake Urmia (Little Zab River) saw a different scenario, with new materials from the middle or late Uruk periods. However, the Zagros highland region (including the Urmia basin) was clearly not a monolithic 'Ubaid-related' culture area throughout most of the 5th and the beginning of 4th millennium BC, but rather an environmentally and culturally diverse mosaic with its own strong local ceramic and, presumably, cultural tradition (Henrickson 1983.379). Conclusion Although we are now in a much better position than before to discuss the Chalcolithic period of NW Iran and its subsequent developments, there is still much to be learned about the development and meanings of the material culture and the processes of change and distribution patterns during the 5th millennium calBC. The available data, new 14C radiocarbon dates from recent excavations in NW Iran, provide a welcome opportunity to rethink 5th and 4th millennium calBC chronology. From what is currently available, we suggest that the Dalma period lasted some 500 years, and dates to between c. 5000-4500 calBC. During Fig. 10. Typical Late Chalcolithic (Pisdeli Type) pottery from Dava Goz. the mid-5th millennium or slightly later (post-Ubaid: 4500-4200 calBC) black-on-buff, so-called Pisdeli culture (LC1 = Kul Tepe Jolfa VII, Dava Goz II) was gradually replaced throughout the southern, western and northern regions of the Lake Urmia Basin. Late 5th millennium chaff-tempered or chaff-faced ware appears alongside Ubaid-related black-on-buff during LC 2-3 (Kul Tepe VIB and VIA, Dava Goz III: 4200-3800 calBC) in NW Iran. To sum up, the emerging picture suggests that the CFW system, whose focus was the highlands, was progressively challenged during the 4th millennium in the north as in the south, by the Kura-Araxes and Uruk expansions, respectively. After a period of coexistence with both, the CFW culture was superseded in the highlands by the Kura-Araxes phenomenon, whose driving forces probably had some decisive advantage over its regional neighbours: judging by the importance of metallurgy and mining activities in the Kura-Araxes world, this advantage could have been technological.
